description `Despite being nominally in the habitable zone, this planet's surface is continually scorched by flares from the system's stars, steadily blasting away its atmosphere. Although some small research stations are present in orbit, providing valuable insights into the nature and behavior of flare stars, the researchers generally avoid descending to the planet's surface unnecessarily.`

description `The world of Aspiration appears to be a mild, habitable world, but one currently in an advanced ice age now slowly retreating. The equatorial region of the planet is warm and comfortable, a cool temperate at the present time. The native biosphere seems to be mostly grasses and something resembling pine trees. In a few thousand years, it might look similar to Earth before it was paved over. For now, it's a sparse world with a single major town built on a promontory, overlooking a wide river mouth which carries runoff from continental scale glaciers to the sea.`
spaceport `The spaceport on Aspiration is a spaceport in the same way that an airport at a regional town is an airport. It has the most minimal facilities to handle a ship landing without disturbance to the nearby town, and that is it. There are no shops or stalls. Aspiration is not on any trade routes and it does not expect visitors. A lone freighter is parked permanently on the outskirts.`

The best known of these is a species of large fish-like creatures with flowing bioluminescent fins that glow in ethereal pinks and purples, the beauty of which prompted many citizens of the Paradise Worlds to demand that the Republic designate this moon as a nature preserve.`

If the air pressure is broadly tolerable, so is the gravity.

I'll admit I'm not particularly well-versed in planetary geography, but what I'm trying to say here is that the air pressure is only tolerable on high mountain peaks, not at ground level.
To the best of my knowledge though, there's quite a large degree of variability in atmospheric pressure relative to gravity - see Earth vs Venus, or Titan vs Ganymede, and I've seen discussions of Earth-like (in size) exoplanets being projected to have thin or no atmospheres in some circumstances too.

Air pressure is proportional to gravity. If there is a place where you can land and tolerate the air pressure pretty well (without also needing protective gear because it's corrosive or whatnot), then at that place you can also tolerate the gravity pretty well.

Titan has similar pressure to earth because it's atmosphere is made up of much heavier stuff, and is super cold.
Venus atmosphere has much greater pressure than earth because it's made of of much heavier stuff, and is super corrosive.

If you can safely step outside with just oxygen gear at a particular level in the atmosphere, you can also tolerate the gravity at the same level as well.

I don't think that's right. At the top of Mount Everest, the atmospheric pressure is about one third of that at sea level, and the gravity is almost exactly the same as at sea level. To take a more extreme example, the gravitational pull experienced at the altitude of the ISS' low earth orbit (400km) is less than 10% less than at sea level, but the atmospheric pressure is zero. To experience half the gravitational pull, you need to travel 2,600km above Earth's surface.
As far as I can tell, atmospheric pressure is the result of the weight (i.e. mass times gravity), of all the atmosphere above a particular point, so it would be increased by increasing the mass of the atmosphere or by increasing the strength of gravity. But as you move up, an increasing portion of the atmosphere is now below you rather than above, and hence isn't weighing down on the atmosphere where you are.

And at the top of Everest you need more than just oxygen gear because it's cold enough to kill you, and quite quickly.

If you can safely step outside with JUST oxygen gear at a particular level in the atmosphere, you can also tolerate the gravity at the same level as well.

This isn't right. Atmospheric pressure will depend upon a number of factors, such as the atmospheric density, the mass of atmosphere on the planet, the temperature, and the altitude. While pressure is proportional to gravity, the top of a mountain doesn't have lower air pressure because gravity is lower there (it barely changes compared to sea level), it's the elevation that reduces atmospheric pressure.

For the love of god I don't have the time or the crayons for this, but at the very least you need some protection from wind chill to otherwise be there with only breathing gear.

Gravity and wind chill are two separate things though. If you want to argue that it would be too cold to step outside with only oxygen gear, that's one thing, but that's different from your previous argument that the air pressure would necessarily be intolerable.

It's a combination of things. With the given combination as it stands, either the temp is cold and wind chill will freeze you, or the temp is warm and the wind will suck the moisture from you and you'll die of dehydration quicker than the gravity will be an issue.
And even that possibility is falling into an extremely narrow range of only hypothetically plausible possibilities.

air pressure would necessarily be intolerable.

And I didn't say it would necessarily be intolerable, I said that either the pressure would be intolerable, or the atmosphere would kill you other ways - which remains consistent with my point.
